The Reader-Writer Problem is a classic synchronization issue in operating systems (OS) and concurrent programming. It revolves around the challenge of managing shared resources, specifically a data structure or a section of code, that is accessed by multiple threads. The problem arises when balancing...

If the current thread already has the writer lock, no reader lock is acquired. Instead, the lock count on the writer lock is incremented. This prevents a thread from blocking on its own writer lock. The result is exactly the same as callingAcquireWriterLock, and an additional call toRelease...

结果与调用 AcquireWriterLock完全相同,释放编写器锁时需要对 进行额外的调用 ReleaseWriterLock。 AcquireReaderLock 支持递归读取器锁请求。 也就是说,线程可以多次调用 AcquireReaderLock,这每次都会递增锁计数。 每次调用 ReleaseReaderLock 时,必须调用 AcquireReaderLock一次。 或者,可以调用 ReleaseLock 将锁计数立即...
